Question

【题目】Scientists in UK have grown a living human “brain”. The team at Aston University created tiny bunch of cells which act like a mini nervous system.

They believe it could help find a cure for worse mental conditions like Parkinson’s disease. Professor Michael Coleman is leading the research program. He explained，“We are aiming to be able to study the human brain at the most basic level, using an actual living human cell system. Cells have to be alive and operating efficiently to enable us to really understand how the brain works.” The experiment involves changing cells from a cancer tumor(肿瘤) and making them behave like brain cells.

Although far from finished, researchers hope the false brain cells will give them a greater understanding of how real brains work. This, in turn, could significantly further research into conditions which affect the brain. Neil Hunt, chief leader of the research group, said，“It is still very early days, but in the future the research could lead to a useful tool for looking into dementia (痴呆)．”

The technique could also provide a way to carry on animal test and is being supported by the Humane Research Trust (HRT). The scientists predict that over the next ten years a million people will develop dementia. Professor Coleman believes their findings could change this. He said，“We hope our research will provide scientists with a new and highly relational human experimental model to help them understand the brain better and develop new drugs to control the related disease. However, the biggest challenge at present is that we are greatly short of fund, which will slow our research.”

【4】B

【解析】

试题分析：本文是一篇科普类说明文。主要介绍了英国科学家们正在进行培养脑细胞的实验，希望通过这样的实验能更好地理解人类大脑结构，从而帮助人们治疗一些脑部疾病。

【1】选C 细节理解题。根据第二段中的““We are aiming to be able to study the human brain at the most basic level, using an actual living human cell system. Cells have to be alive and operating efficiently to enable us to really understand how the brain works.” .”可知，他们希望通过这样的研究试验来理解人脑是如何工作的。故选C。

【2】选D 细节理解题。根据第三段最后一句中的“It is still very early days, but in the future the research could lead to a useful tool for looking into dementia (痴呆)．”可知，现在研究尚处于初期，但将来可能会成为研究痴呆疾病的有效手段。故选D。

【3】选D 细节理解题。根据最后一段最后一句However, the biggest challenge at present is that we are greatly short of fund, which will slow our research.”可知，现在研究最大的问题是缺少资金。故选D。

【4】选B 写作意图题。本文属于科普类说明文，主要介绍了英国科学家们正在进行培养脑细胞的实验，希望通过这样的实验能更好地理解人类大脑结构，从而帮助人们治疗一些脑部疾病。故选B。
